CD214L-T110CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T110CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This surface-mount component features a 110V reverse standoff voltage with 177V maximum clamping voltage and 16.8A peak pulse current capability in a DO-214AB (SMC) package. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the CD214L-T110CALF is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage - Reverse Standoff: 110V (nominal)
Voltage - Breakdown: 122V (minimum)
Voltage - Clamping: 177V (maximum at Ipp)
Package / Case: DO-214AB, SMC (surface mount)
Bidirectional Channels: 1
Type: Zener diode
Applications: General Purpose

Substitute parts are grouped into two categories:

Direct Equivalents maintain all key electrical parameters (standoff voltage, breakdown voltage, clamping voltage) and identical peak pulse current ratings (16.8A ± tolerance) with 3000W peak pulse power. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Equivalents maintain all voltage parameters and package compatibility but differ in peak pulse current capability (ranging from 8.4A to 28.3A) and corresponding power dissipation (1500W to 5000W). These parts are mechanically compatible but require circuit-level evaluation to confirm suitability for the intended application's current and power requirements.

Engineering Selection Recommendations

Primary Recommendation: SMLJ110CA (Bourns Inc.)

SMLJ110CA is the direct equivalent replacement for CD214L-T110CALF. Both parts are manufactured by Bourns Inc. and share identical electrical specifications: 110V reverse standoff, 122V breakdown voltage, 177V clamping voltage, and 16.8A peak pulse current with 3000W peak pulse power. SMLJ110CA is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). This part provides seamless substitution with no circuit redesign required.

Secondary Recommendation: SMDJ110CA-T7 (Littelfuse)

SMDJ110CA-T7 maintains all critical voltage parameters and delivers 16.9A peak pulse current with 3000W peak pulse power, closely matching the original specification. Manufactured by Littelfuse with active product status, ROHS3 compliance, and extended operating temperature range (-65°C to 150°C), this part is suitable for applications requiring enhanced low-temperature performance. Electrical compatibility is confirmed across all voltage ratings.

Alternative for Higher Current Applications: 5.0SMDJ110CA (MDE Semiconductor Inc)

5.0SMDJ110CA maintains all voltage specifications but provides 28.3A peak pulse current and 5000W peak pulse power. This part is appropriate only for applications where the original circuit design can accommodate the higher current capability. MDE Semiconductor Inc. manufactures this part with active status and ROHS3 compliance. Selection requires confirmation that the higher current rating does not introduce thermal or reliability concerns in the target application.

Not Recommended: SMCJ110CA Series (Fairchild Semiconductor, Littelfuse)

SMCJ110CA, SMCJ110CA-HR, SMCJ110CA-HRA, and SMCJ110CA-HRAT7 deliver only 8.4A to 8.5A peak pulse current with 1500W peak pulse power. These parts are electrically compatible at the voltage level but provide insufficient current capacity for applications designed around the 16.8A specification of CD214L-T110CALF. Use of these parts in such applications risks inadequate transient suppression and potential component failure.

Frequently Asked Questions (FAQ)

Q: Can SMLJ110CA directly replace CD214L-T110CALF without any circuit modifications?

A: Yes. SMLJ110CA is a direct equivalent with identical electrical specifications (110V standoff, 177V clamping, 16.8A peak pulse current) and the same DO-214AB package. No circuit redesign is necessary.

Q: What is the difference between SMDJ110CA and SMCJ110CA?

A: Both parts maintain the same voltage ratings (110V standoff, 177V clamping) and DO-214AB package. The primary difference is peak pulse current: SMDJ110CA delivers 17A with 3000W power, while SMCJ110CA delivers 8.4A with 1500W power. SMDJ110CA is suitable for applications requiring higher transient current suppression; SMCJ110CA is suitable only for lower-current applications.

Q: Is the 5.0SMDJ110CA a suitable replacement for CD214L-T110CALF?

A: 5.0SMDJ110CA maintains all voltage specifications and is mechanically compatible. However, it delivers 28.3A peak pulse current versus the original 16.8A. This part is suitable only if the circuit design can accommodate the higher current capability without introducing thermal stress or reliability degradation. Circuit-level evaluation is required.

Q: Do all substitute parts have the same operating temperature range?

A: No. CD214L-T110CALF and most substitutes operate from -55°C to 150°C. However, Littelfuse parts (SMCJ110CA-HR, SMCJ110CA-HRA, SMCJ110CA-HRAT7, SMDJ110CA-T7) extend the lower limit to -65°C. SMLJ110CA-TP extends the upper limit to 175°C. Verify temperature requirements for your application before selection.

Q: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original CD214L-T110CALF is also ROHS3 compliant. Compliance status is consistent across all recommended alternatives.

Q: What packaging options are available for these TVS diodes?

A: All parts in this comparison use the DO-214AB (SMC) surface-mount package. Packaging is consistent across the main part and all substitutes. Tape & Reel (TR) and Bulk packaging options are available from various manufacturers but do not affect electrical or mechanical compatibility.

Q: Can I use SMCJ110CA-HRAT7 as a replacement if SMLJ110CA is unavailable?

A: SMCJ110CA-HRAT7 is not recommended as a direct replacement. While it maintains voltage compatibility (110V standoff, 177V clamping), it delivers only 8.5A peak pulse current versus the required 16.8A. This insufficient current capacity may result in inadequate transient suppression. Use only if circuit analysis confirms that lower current capability is acceptable for your application.
